Granted: 2004-12-21
Abstract: L'invention concerne une bûche de foyer synthétique bon marché et écologique, fabriquée par mélange d'un carton mince ciré spécialement traité (ou autres papiers couchés cirés de différentes tailles) avec un liant/combustible. Le liant/combustible est constitué de cire de pétrole ou d'un mélange de cires, dont la nature et la teneur sont modifiées de manière appropriée par adjonction in situ d'une paraffine déjà présente dans le carton mince ciré. De la sciure de bois ou d'autres bouche-pores peuvent également y être ajoutés. Après incorporation homogène de ces matières, le mélange obtenu est extrudé, moulé, comprimé, ou autrement formé, si bien que la masse qui en résulte est suffisamment solide pour conserver sa forme à température ambiante normale.

Title: Deflecteur de faisceau et detecteur a balayage
Inventor: AYE TIN M
IPC: G02F1/03
Filed: 1999-08-24
Granted: 2006-12-05
Abstract: L'invention concerne un déflecteur de faisceau (40) comprenant deux réseaux de microprismes connectés (42 et 48), l'un d'eux consistant en un matériau d'indice de réfraction variable (48) modulable en fonction d'un champ dont l'amplitude ou l'intensité est régulée par action sur la tension appliquée. De préférence, l'autre réseau (42) consiste en un matériau d'indice de réfraction constant. Une couche conductrice (102, 104 et 82) est placée des deux côtés du réseau d'indice de réfraction variable. De préférence, un panneau (68 et 70) est placé devant et derrière les réseaux. Deux paires de ces réseaux peuvent être placées en parallèle, leurs microprismes étant généralement perpendiculaires de façon à former un déflecteur à deux dimensions. Pour obtenir un temps de réponse de déviation inférieur à 100 microsecondes environ, chaque prisme a une hauteur ne dépassant pas 20 micromètres environ et une largeur ne dépassant pas, de préférence, 100 micromètres environ. De préférence, chaque hauteur de prisme est inférieure à 15 à 10 micromètres environ pour obtenir un temps de réponse de 30 microsecondes ou plus court. Pour fabriquer le déflecteur on utilise un procédé de lithogravure pour faisceau électronique à inscription directe de façon à réaliser un original permettant de faire la réplique de réseaux dont la hauteur n'excède pas 10 micromètres. Une paire de déflecteurs peut être utilisée pour dévier un faisceau en deux dimensions et servir dans un détecteur à balayage. Si le faisceau est un laser, le déflecteur peut être utilisé dans un ensemble à radar pour imagerie laser. Ces types de détecteur à balayage et d'ensemble permettent un balayage rapide d'un objet ou d'une région de manière avantageuse sans nécessiter le déplacement du déflecteur pendant le balayage.

Abstract: Label applicator apparatus (10) for applying a self-adhesive label (12A) to a surface (16) which is movable relative to the apparatus.  The label is carried on an elongate backing web (14) having a plurality of labels (12) adhered to one side thereof in longitudinally spaced relationship. The apparatus includes an edge (22) over which the web is drawn whereby, when a force is applied along the web which exceeds a peeling threshold, the web is peeled away from the label and the label is dispensed at the edge. The apparatus includes pressing means (24) located a set distance from the edge for pressing the label against the surface as it is dispensed, thereby adhering the label to the surface, and means (28, 30) for applying a peeling force which is greater than the peeling threshold during dispensing of at least an initial portion of the label which spans the set distance to initiate dispensing of the label. The peeling force is operative during dispensing of the initial portion of the label and is inoperative during dispensing of a final portion of the label, wherein when the peeling force is inoperative, dispensing is continued due to an additional force being exerted along the web by a portion of the label which is adhered to the surface.

Abstract: An apparatus modulates the phase of an optical signal. The apparatus includes an optical medium (110) for propagating the optical signal. At least one electrode (130, 132) is positioned in proximity with the medium (110). The electrode induces an electric field within the medium in re-sponse to an AC voltage to produce varia-tions in the index of refraction of the optical medium (110) through the electrostrictive effect. Preferably, the phase of the optical signal is modulated such that polarization components of the optical signal parallel to and orthogonal to the electric field experience an equal phase shift. In certain embodiments, a DC voltage is supplied to the optical medium. Alternatively, the DC voltage within the optical medium may arise from poling the optical medium. Certain embodiments of the present invention include two electrodes positioned on opposite sides of the optical medium. The apparatus is used in an interferometer to form modulation device or switching device.

Abstract: Transmitter architectures for a communications system having improved performance over conventional transmitter architectures. The improvements include a combination of the following: faster response time for the control signals, improved linearity, reduced interference, reduced power consumption, lower circuit complexity, and lower costs. For a cellular application, these improvements can lead to increased system capacity, smaller telephone size, increased talk and standby times, and greater acceptance of the product. Circuitry is provided to speed up the response time of a control signal. The control loop for various elements in the transmit signal path are integrated. A gain control mechanism allows for accurate adjustment of the output transmit power level. Control mechanisms are provided to power down the power amplifier, or th e entire transmit signal path, when not needed. The gains of the various elements in the transmit signal path are controlled to reduce transients in the output transmit power, and to also ensure that transients are downward.

Title: Metal detector
Inventor: BRITTON ANDREW MICHAEL
IPC: G01V3/10
Filed: 2001-03-06
Granted: 2010-10-12
Abstract: A metal detector has a circular excitation coil (10) through which foodstuffs to be tested (65) pass, on a conveyor belt (40). The excitation coil (10) is excited by a stable oscillator (50) and the lines of flux generated by the excitation coil (10) link two receiver coils (20, 30) equidistantly spaced either side of the excitation coil (10). As a foodstuff (65) having a foreign ferromagnetic or electrically conductive object therein passes through the receiver coils (20, 30), a voltage is induced in them. This induced voltage is phase compensated. The change in amplitude or frequency of the oscillator (50) as the foodstuff (65) moves through the excitation coil (10) is also passed to the processor (70) which removes the artifacts from the detector signal caused by the volume of the foodstuff (65) itself. The resultant signal, which was previously swamped by the effect of the volume of the foodstuff itself, can then be detected and the foodstuff can be removed from the conveyor (40).
